    [turbofan] Implement throwing exceptions into TurboFan code.

    This extends the stack unwinding logic to respect optimized frames
    and perform a lookup in the handler table to find handlers. It also
    contains fixes to the API call stubs to allow a stack walk while
    promoting scheduled exceptions.
